A long intermediate terrace house designed for a multi-generational family unfolds vertically across five floor plates on a narrow urban site measuring just 6 metres wide and more than five times as long. The project addresses the dual challenge of accommodating a large household—comprising a couple, their parents, four children, a live-in helper, and occasional guests—while ensuring that every space enjoys ample natural light and a strong sense of connection.

The architectural response centers on carving out a continuous vertical void that spans all five levels. This void becomes the spatial anchor of the home, drawing daylight deep into the plan and providing clear visual orientation throughout. Living spaces and bedrooms are arranged to overlook this central volume, allowing light, air, and movement to flow freely across floors while reinforcing a sense of togetherness within the household.

Given the tight envelope controls and the depth of the site, mezzanine floors are introduced and floor- to-floor heights are carefully calibrated to increase usable area without sacrificing comfort. This approach enables the required number of rooms to be efficiently accommodated within the narrow footprint. Each room is conceived as a distinct box suspended between the party walls and positioned around the void to maximize access to daylight and views across the interior.
